- Reviewed in Canada on May 28, 2023Verified PurchaseUpdate January 2024: I now have two separate systems, one installed at our seniors club plus the original at home, both logged on to wifi. And a fancy outdoor Govee string light. I can monitor temperatures while traveling, both at the club and at home. The second Govee thermometer came with six sensors and I added three of them to the three already at home on the old receiver for a total of six sensors plus the light string. The remaining three sensors are installed at the club with the new receiver. The documents with the new system said the receiver could handle 10 devices. I wonder if this is due to the firmware update. So both the old receiver and the new receiver can handle 10 devices as of January, 2024. On the Govee app I see all 10 devices (7 at home, 3 at club) although the uploaded image is only showing eight.
Previous review of April 2023: A very dependable system.
A month ago I set this up on our wifi and installed the sensors in the greenhouse. The sensors have never lost contact with the receiver and that’s great because it’s been a problem with another brand. The app is great because it’s easy to use, As expected, I can travel and check greenhouse conditions from afar. The receiver has never lost the wifi connection despite power outages and wifi reboots. The temperature/humidity alarms are easy to set up. I just discovered a new feature writing this review- I can squeeze the timeline to the date range I want as shown in the second image. The Govee wifi thermometer has made it easy to monitor greenhouse conditions.

- Reviewed in Canada on January 22, 2025Verified PurchaseI use this way more than I expected! I originally wanted it to keep track of the temp in my kids rooms, but I use it all the time when I’m away to make sure the temp is stable.
The app is super easy to use. You can use it through Bluetooth if you are in range, or WiFi when you are out of the house.
Great value for what you get.
- Reviewed in Canada on May 15, 2025Verified PurchaseExcellent! Works well
- Reviewed in Canada on October 27, 2024Verified PurchaseI hate using smarthome apps. In fact, apart from the mandatory setup, I will never use them again. I connect everything to Alexa and ask it for the information what ever device I am interested in, including GoVee. The Govee temperature sensors seem to be well made and I have a high degree of confidence they will survive -30C freezes that we can get in Eastern Ontario. I can ask Alexa for most of the information that the Govee app provide (which is just the temperature 99% of the time)
Set up in the Govee app is clean, easy and quick. Connection to Alexa is also very straightforward
Recommended.
- Reviewed in Canada on January 12, 2025Verified PurchaseI use these inside my snakes enclosure to monitor her temps when I’m away from home for a day or a few hours. Works well and seems very accurate. Love that you can set a range of temp and homily and it will notify you when it exceeds or drops below your pre set temps.

Reviewed in Canada on August 30, 2024Verified PurchaseRien a dire de négatif . Application intuitive , très précis dans les rapports , possibilité de consulter les appareils à distance , garde en mémoire les rapport de température et humidité, possibilité d'aller chercher le point de rosé... Détecte très bien un changement / comportement de mon échangeur d'air et d'un déshumidificateur. Sur le graphique de la photo ci-joint on peut voir les petites ligne regroupé ( représente avec déhumififateur activé dans la pièce et échangeur d'air ) et par la suite avec déshumidificateur de désactivé et seulement échangeur d'air . La différence se fait très bien remarqué.

- Reviewed in Canada on August 2, 2024Verified PurchaseSo I purchased these to add to my Home Assistant setup and replace a couple failing DHT11 sensors.
First - 4 stars because I find the App a bit meh. But - I'm not really someone that likes using Smartphone Apps - so take that with a grain of salt... And at this time, it's the only reason I didn't give 5 stars.
I purchased these, hoping the Wifi adapter might be accessible via HA, but alas, it is not. I thought about adding a Bluetooth Dongle to my HA instance, but since I'm running HA in a VirtualBox guest instance, and there seems to be some question as to stability of Bluetooth with this setup, I opted to go with a different solution.
So I added an ESP32 board (/dp/B0C9VSYS4N?th=1) to HA and set it up as a Bluetooth Proxy - AND BAM!!! It immediately discovered the three Govee H5100 sensors and asked if I wanted to add them to HA - then led me through the addition and setup. After that, I unplugged the Govee Wifi adapter and I now have three H5100 sensors feeding temperature and humidity data to my HA dashboard. In addition, the sensors report the condition of their batteries, so I know when to replace their batteries.
Overall, very happy with these, but I am a little concerned about how the one outside on my deck will handle the -30C temperatures I get during a few days in the winter. But no problem with the heat wave and 48.7C temperature on the deck a few days ago...
